About Blue Water Facts
Blue Water Facts is built and maintained by a small editorial team of supply-chain professionals who got tired of the same three problems: opaque carrier directories that haven't been updated since 2015, container prefix lookups that return paywalled answers, and "transit time" calculators that quote one-vessel-direct numbers when every shipment in the real world trans-ships at least twice.
So we built the reference we wished existed. Our database covers 265 ocean carriers, 34 working trade-lane corridors with realistic transit-time reporting, 6 ocean alliance profiles, and the complete inventory of 15 standard ISO container formats. Every page is human-edited. In July 2026 an internal audit found that our per-carrier ISO 6346 owner-prefix registry could not be reliably verified against the Bureau International des Containers for most long-tail carriers, so we removed that feature (see /accuracy/ for the full findings). All other figures are referenced to public carrier data where available, and every record is updated on a quarterly cadence.
Blue Water Facts is reader-supported. We accept advertising in the form of contextual display units (clearly labelled as Sponsored) and we partner with a small number of editorial sponsors whose links appear in the sidebar and footer. We do not accept payment for inclusion in our directory and we do not write paid carrier reviews. If you find an error in our data, please write to editor@bluewaterfacts.com with a public source and we will correct it within 48 hours.
You can begin exploring the reference from any of the four main hubs:
- Carriers — full directory of 265 ocean container carriers worldwide.
- Trade lanes — 34 port-pair corridor reports.
- Alliances — Gemini, Premier, Ocean Alliance and historical partnerships.
- Container formats — every ISO container type with full dimensions.
